A fun, offbeat retreat – although it's a bit of a buzz-kill for foodies – this veritable parasite safari will probably encourage you to cut back on your sushi intake. Although there isn't much English signage, you'll still get a kick out of the rows of formaldehyde-preserved critters, which are labelled with their Latin names (don't miss the 8.8m-long tapeworm!). Upstairs, the lab-coat-donning staff also sell various parasite-themed trinkets and T-shirts to guffawing Japanese girls.
